I have a Manfrotto 3421 Head (gimbal type) and the problem is they don't make an L bracket for it. It is a pain to carry around 2 tripods when I use those lenses that do not have a tripod collar and need to shoot portrait.
It looks like the piece that holds the plate will unscrew from the actual head, but I don't know if there are any arca-swiss pieces that will fit it. It would sure save a bundle if I can just replace the plate holder (& plates) so I don't have to get a $400+ head. Anyone know if that piece can be replaced?
